Defensive publication

ABSTRACT

DISCLOSED IS A POWDER COATING COMPRISED OF AN ADMIXTURE OF A CELLULOSE ACETATE BUTYRATE, AN ADDITION COPOLYMER OF METHYL METHACRYLATE AND ETHYL METHACRYLATE AND A PLASTICIZER. THE COATING CAN BE APPLIED TO A HEATABLE SUBSTRATE IN POWDER FORM AND CAUSED TO FUSE BY APPLICATION OF HEAT TO PRODUCE A DESIRABLE COATING HAVING AN UNOBVIOUSLY HIGH RESISTANCE TO HYDROLYSIS.
